My opinion is deeper than what you think. Vitalik is a really smart guy and I think he did that merge because of the the regulations from SEC.
Imagine energy consumption used for Ethereum mining and now with PoS is 99% lower than PoW. So 80% of the DeFi project are on the Ethereum network. And institutional investors will be quite interested in the new financial opportunities.
Which mechanism do you like more PoW or PoS? Why?
